    Patch Lady Susan here on an issue I’ve been tracking since the January updates came out.  I have been concerned seeing consumers, consultants and folks in Enterprises impacted by an issue whereby after the January Spectre/Meltdown updates, the systems will reboot and the error message “Inaccessible Boot Device” is received.  At that point in time, you have a nice door stop until you can get the computer working again.  The KB above finally gives official guidance and acknowledges the issue. Based on a forum thread I’ve been following, it appears that the acpi.sys driver somehow gets mangled during either the install of updates or rebooting process.

    As I live in California where we are urged to have an Earthquake readiness kit at all times, I’ll urge you to have a “Computer incident meltdown” kit at all times.

    Step one: Make a bootable flash drive of Windows 10 from the Windows media installation site.  Should you need to boot “under” the operating system to get to a command prompt, this media will do the trick.

    Step two: Have a backup of your programs, your key install codes, or anything else you’d hate to lose.  For standalone pcs, a nice external usb hard drive.  Your Windows 10 operating system and drivers for your pc will more than likely reinstall from even a base operating system reinstall, what you need to keep is installer downloads, product keys, photos, documents and anything else you’d cry or get really mad at someone at Microsoft if your system had to be totally rebuilt.  Of course you can also use a third party backup tool to completely backup your Windows 10, but bottom line, think of the items and software on your computer that would be hard to replace.
